it is interesting to note that many of those who know what they are doing carry two mini bics, and backup matches. hmmm ..

piezo ? had a StormProof turbo lighter for almost an hour one time. what a pos, though it had a remarkably tough case, with a bit of effort, it crushed sweetly in my vise.
it was a good investment too, beause for only $32 i still have reliable fire starting.
